SHOE-BOTTOM-FILLING MACHINE.

Application filed November 5, 1919. Serial No. 335,860.

To all whom it may concern:

Be it known thatI, OLIVER D. Hooon, a citizen of the United States, and resident of Brookline, in the county of-Norfolk and State of Massachusetts, have invented an Improvement in Shoe-Bottom-Fillin Machines, of which the following description, in connection with the accompanying drawings, is a'specification, like letters on the drawings representing like parts.

My present machine is intended primarily for use with a hot filler, preferably the kind set forth in U. S. Patent No. 861,555 of July 30, 1907, which even when hot is only sluggishly fluid and hence tends to flow slowly instead of rapidly. The expert hand operator, however, has attained such skill and speed that an automatic or semi-autoniatm machine must operate with extreme rapldity in order to compete successfully with the hand operator. To this end therefore have provided a machine which combines 1n its use the skill of the operator and convenient filler delivery mechanism for acceleratlng the delivery and means for distributing, leveling and condensing the'filler properly in the shoe bottom. All this is so combined and coordinated that the operator can get the benefit of the use of both hands, one hand in manipulating the shoe while the other hand manipulates the delivery end of the machine. Preferably the delivery open-' ing is controlled by the'shoe (as. herein pro-' vided, in'the hand of the operator) and the filler delivering or ejecting 'mechanism is normally quiescent but is rendered instantly operative by the movement of the valve or delivery controlling device. In other words my machine provides an ejector normally quiescent but rendered operative by the opening of the delivery orifice which, being under the control of the operator, enables the operator to control at all times the amount of filler delivered.

Further features, combinations and advantages of my invention will be set forth at length in the following detailed description taken in connection with the accompanying drawings in. which ,I haveillustrated the preferred embodiments ofmy invention. In the drawings Figure 1 is a central vertical cross-sect n l View facing t e front of machine- Specification of Letters Patent. Patented July 26-, 1921.

Fig. 2 is a horizontal sectional view taken approximately on the line 2-2 Fig. 1.

Fig. 3 is .a vertical transverse sectional detail on line 3 3 Fig. 2. i

Fig. 4 is a vertical transverse sectional detail taken on the line 4& Fig. 2.

At the upper end of the machine as herein shown is a'hopper 1 ofany suitable size and shape maintained properly warm by any suitable means as by a steam or hot water jacket 2 and at the lower end thereof is a delivery portion herein shown as a tube 3, also steam jacketed indicated at 4:. This tube 3 carries at its lower end a shoe or casting 5 shown as screw threaded thereon at 6 and having sloping walls 7, 8 on its interior affording a restricted outlet or nozzle opening 9 closed by a valve 10 normally held downward in closing position by a spring 12. This valve has a downwardly projecting stem or finger 13 in position to be engaged by the bottom of the shoe when the shoe is pressed upwardly against the same to open the nozzle forthe'ejection of filler. W ithinthetube 3 is an ejector which may be of any convenient construction, being herein shown as a screw or'wormconveyer 14 for giving a sudden downward impulse to the filler in the tube whenever the screw is rotated. This screw is operated by a rod 15 and a drive pulley 16, the latter running normally idle and the rod 15 being h'erein shown as provided at its upper end with a magnetic-clutch 17. This clutch may be ofany usual kind and therefore is not herein shown in detaiL. The clutch is connected byfa circuit 18, 19 whose poles 20, 21 are in position to be-engaged by a circuit .closer or contact plate 2 2-mountedin insulated positionon the rear projection 23 of the arms 24.- which carry the valve 10 pivoted at 25 to the casting 5. Thus whenever the operator 'strikesthe bottom ofthe shoe up against'the stud or" finger 13 he instantly'opens the orifice by raising the valve 10 and at the same instant closes the circuit of the electric clutch and gives a sudden start or'ejectin'gimpulse to the screw so that the filler. is forcibly shot out into the shoe andhe' can therefore get the required amount of filler" almost instantly into the.

shoe bottom for filling the shoe bottom; and

thereupQIl'bS? immediate y lower -t e sufficiently to permit-the valve to close the orifice and break the circuit of'the ejectortso that the screw 14 stops.

At one side herein shown as at the right hand side of the filler orifice is a projecting arm 26 maintained suitably warm by any convenient means herein shown as by a coil 27 and shown as having a V shape in cross section; see Fig. 3; with opposite slanting walls 28, 29 and an intermediate edge or V 30. At the opposite side of the orifice is a fiat plate 31 alsov heated by suitable means as by a coil'32. Thus when the operatorihas caused the desired amount of filler to be deposited in the shoe bottom in a small heap which may be elongated in its delivery simply by sliding the shoe lengthwise-under the orifice, heinstantly levels down this heap of filler by engagement with the arm 26 and then strikes the shoe bottom with its loosely leveled'filler upward against the hot plate 31 which condenses the filler.

To enable the operator to bring all the aforesaid mechanism into the most speedy cooperation'on the shoe bottom I have provided the lower end of the apparatus with a handle 33 and'have mounted the lower end and ejector -apparatus on a universal joint 34." The screw Hand rod 15 are connected also by universal joint 35. Thus'as soon as the operator has caused the right amount of filler to b'e deposited'in the shoe bottom he starts'to move the shoe toward the right with hisleft hand and at the same time with his right hand grasping the handle 33 he swings the arm 26' toward the left to meet the shoe and by a deft movement of shoe and handle causes'the arm 26 to perform its leveling and spreading movement and then by an oposit-e movement of the arm and shoe he brings the plate 31 and shoe into forcible contact which condenses the filler and completes the leveling operation.

In practice the hopper 1 is loaded with filler which is brought to the desired degree'of plasticity or SGIIll-fllllClltY. Then the operator seizes the shoe in the usual manner in his left hand and strikes it against the stud or finger 13 which raises the valve 10, therebyopening the orifice 9 and at the same time starting the ejector 14c'which forcibly ejects the filler in the amount desired according to the control ofthe operator: This control is accomplished by lowering,

the-shoe at the critical moment which closes the orifice and'stops the ejector; He then swings the shoe toward the arm 26* and swings the arm toward the shoe so that the two come into cooperating leveling relation'instantly and this is followed by an opposite swinging. movement which brings the shoe bottom and plate 31 into proper pressing relation to each other; The arm 26 performs its function of smoothing'and lev ellng w th facility in cooperation the tipping upwardmore or+less of the shoe bottom tocooperate with the slantingfwalls 28, 29 of the arm. The object of this construction is to enable the operator to shove the filler conveniently forward or backward or to one side or the other side in the shoe bottom cavitv and at the sametime smooth it down so as to insure that every point of the shoe bottom cavity is properlyfilled.

As already intimated, my invention is capable of awide variety of mechanical embodiments and accordingly I wish it understood that I am not limited to the specific.

mechanisms having provision for enabling the operator to simultaneously control them.

both and thereby control the amount of filler delivered to the shoe bottom.
